We observed that ECG changes associated with high levels of sporting activity are reversible in the majority of cases after cessation of the sports career. This is probably related to the normalization of the raised vagal tone and diminution of the effort-related heart hypertrophy and chamber dilatation in ex-sportsmen. The persistent ECG changes observed in some of the ex-sportsmen could be related to the ageing processes observed in the general population as well. It is important that all ECG deviations in ex-sportsmen be considered seriously and interpreted in the context of the ECGs obtained during the active sports career.

Acute effect of aerobic exercise on inhibitory control and task-related heart rate variability in preadolescent children.
Physiol Behav
January 2025
University of Basel, Department of Sports, Exercise and Health, Grosse Allee 6, 4052 Basel, Switzerland.
Objectives: To investigate whether a single session of aerobic exercise improves inhibitory control in preadolescent children and whether this effect is mediated by changes in parasympathetic activity.
Design: In this experimental study, an intervention and control group were pair-matched by age, sex and moderate-to-vigorous physical activity.
Method: 114 participants either completed a 20-min moderately-intense exercise bout on a cycling ergometer or watched a 20-min video.
Angiotensin 1-7 Attenuates the Development of Ischemia-Reperfusion-Induced Arrhythmia in Rats: Electrophysiology, Molecular, and Immunohistochemical Study.
Microsc Res Tech
January 2025
Department of Physiology, Faculty of Medicine, Cairo University, Cairo, Egypt.
Arrhythmia is a common and serious global health problem, contributing to cardiovascular morbidity and mortality. The cardiac muscle is susceptible to ischemia-reperfusion (I/R) injury, which can lead to fatal arrhythmias during open-heart surgery. We investigated the potential prophylactic effect of angiotensin 1-7 (Ang 1-7) using an in vivo rat model of I/R injury and examined the underlying mechanisms.

This is a case of a young, 20-year-old, male Navy recruit who was admitted to our healthcare facility with intermittent atypical chest pain and limiting exertional symptoms and was diagnosed with myocardial bridging (MB) as the most likely etiology of his chest after the complete cardiac workup, leading to his career limitations due to potential risks. Our patient presented with atypical chest pain and limiting exertional symptoms. Chest pain was non-radiating.

The exposure-response analysis was performed using the data from healthy adults participating in a randomized, double-blind, single-dose, four-way (placebo; loperamide 8 mg [therapeutic]; loperamide 48 mg [supratherapeutic]; moxifloxacin 400 mg [positive control]) crossover study. The electrocardiographic measurements extracted from 12-lead digital Holter recordings were time-matched to pharmacokinetic sampling of loperamide/M1.

J Int Med Res
January 2025
Cardiovascular Surgery, University Hospital of Lausanne, Lausanne, Switzerland.
Objective: The definition of coronary artery bypass graft (CABG)-associated myocardial infarction (MI) is controversial because the postoperative increases in cardiac enzyme activities are multifactorial in origin.
Methods: We performed a retrospective case-control study of patients who experienced perioperative MI (cardiac enzyme release, electrocardiographic changes, dysfunction on echocardiography) and those without ischemia to identify risk factors and enzyme activity thresholds.
Results: The estimated incidence of CABG-associated MI was 2.
